NTERLOCKING JOINT FOB. CONTAINERS;

Application filed August 19,1921. Serial No.749333.

To all-whom t may concern:

Be it known that l', CHAnLns E. Soor'r, ai.

citizen of the United States, residing at Derry, in the county of Derryand State of New Hampshire, have invented certain new and usefulimprovements in Interlocking Joints kfor Containers, ofwhich thelfollowjoining together a number of container sec-l tions to form areceptacle, the said sections being so joined as to be separable, onefrom another to permit the taking apart of the container for conveniencein packing and shipping.

additional object is to provide a container of separable sectionsadapted to be joined together by a slot and slide arrangevment at thejoints whereby, when assembling, the sections maybe telescoped onewithin the other, to provide a substantially lirm, leal:- proof joint.

A further objectof the invention is to provide a deviceof the abovecharacter that is simple in construction, strong and durable and whichit is believed may be inanufac` tured at a reasonably low cost.

, Various otherolojects and advantages of the invention will becomeapparent during' the continuance ofthe following descrij'ition.

Figure 1 is a viewl disclosing the manner ot" applying the invention,the parts being` shown in separate and disconnected relation. Figure '2vis a horizontal cross section through a corner or joint of a receptacleconstructed in accordance with the invention, and, f

Figure 3 is a vertical cross sectional view through the corner or jointof the receptacle. In the drawings, 10 and 11 respectively designate theend and sidewalls of a con-y tainer which may be constructed ofany-smt-` able material, preferably metal,best adapted .for the purposein view.

lWhile only one end of each wall of the 'container has been' illustratedin the drav-v ing it is to be understood that both ends are similarlyconstructed andhence the following description applies to theconstruction of forming fold which is obvious.

the joint of each corner oradjacent endsk `of the container section.

yA T-head is formed at each endy icon-i y tainer section 10 preferablyby folding end portion 12 to provide the laterally extending vwings .13extending 'verticallyjon opposite sidesof-the. section and at one end asshown in Figure 1. To retain the folds of the T.-y head -in place, aretaining cap or holding rnernberle is provided which consists inl anelongated head member adapted telit down overy thelateral extensionsandvcarrying a centrally projecting portion 15, which lits overl end 12of the -section and the adjacent portion of the latterfasshown in Figure3 of the drawings. rlhis cap 'is held in place by. frictional engagementwith the section-nap and also by the resiliency of thev latter whichtends to keep them expanded against the inner walls of the foldingmember, thereby securely retaining the latter in place thereon. Section10 has its opposite end provided with oppositely disposed Vfoldedportions 16 Aand 17` extending transversely of the section and spacedapart by an opening 18 wherebya T-slot is provided to receive the T-headof section 10. One en d of section 17 is `extended rearwardly of theT-slot, as shown at 19, and serves vas a reinforcement for the slot-When assembling the sections together, the T-heads at the end sectionsare inserted in the T-,slots of thes'ide sections and slid downwardlytherein until-the top and bottom edgesotl the two sections are mutuallyflush.

Each end sectionhas the cap` 14. attached thereto prior to beinginserted in the slots of .the sidesections ,and after being relativelypositioned, the sections are ultimately locked together by means of anouter'hood vor cap 2O constructed as shown in Figure 1 and designed tolit down over Aand around the T4 vslots for holding` the T-heads firmlytherein.

The outer cap or hood is slotted as indicated at 21, which slot is inalignment with opening 18 of the T-slot and enables the outer cap ltofit down over central portion 18 of the inner cap fory retaining memberla. f

L lt will thus be seen that the sections are relatively locked by a slotand slidearrangement and that the joints are so formed as to precludeany possibility of leakage through ori around the oinedk sections. y

`yFor convenience in packing or shipping the containers in largequantities, they may l. A sectional container be easily dismantled intotheir` component parts bysimply 'removing outer capQO from o `each jointand subsequently disengaging the sections by sliding the "if-headupwardly of 5 the slot. The sections may then be packed in convenientbundles and in large quantities Without occupying an undue amount oi'shipping space.

F rom the foregoing it is believed that the advantages and novelfeatures of my invention Will be readily understood and thereforefurther detailed description 'is deemed un# necessary;

Vilhat is claimed is: f

embodying sections adapted for relative eng gement, some L sectionshaving end portions i'o'lded Aon themselves to provide laterallyentendsrolds adjacent opposite ends of the seclons to provide Teheadsthereointhe other of said sections 'having' opposite vend por tonsfolded upon themselves to provide T-slots for the reception of the'T-heads of the other sections, a retaining'br cap engage-` le a. join-tbetween the said end and side Walls, said retaining` member being heldin place by liricti f nal engagement with Wall of the slot, and alocking member at each slot or joint presenting' a 4hood arranged to ritover and aroundthe T-slotoif the joint for holdingthe T-head firmlytherein, said hood being slotted to accommodate the said centrallyprojecting portion of the said re-4 taining member.

' ln testimony whereof aliix my signature.
